How to Get Rid of Drain Flies

In this video, How to Get Rid of Drain Flies, home renovation brothers Dave and Rich and Dave's son, Caleb, show you two different processes to remove drain flies from your home.

If you are looking for an off the shelf product, you can try this from Amazon:
Fruit Fly & Drain Fly Killer - Simple Commercial Drain Gel Treatment – Eliminates Gross Fruit/Sewer Flies & Gnat Infestations from Any Drain. Fast & Easy - 1 Gallon (128 Ounces)

If you are looking for a more simple product from stuff you already might have around the house we have 2 possible ideas below.
They are both concoctions that you can easily make with ingredients that are probably already in your home.

1) Drain Fly Trap -- in a bowl mix equal parts of:
water
white distilled vinegar
sugar
1/4 cup of the above 3 ingredients works well

mix in 5 - 10 drops of dish soap

stir and leave a trap by each sink, toilet, and bath tub drain

leave overnight, check each day, hopefully you will find less drain flies each day, which means their population is dwindling.

An additional problem is that the drain flies could have been laying eggs in the drain lines. To clear those out, make the following concoction:

2) Drain Fly Egg Remover:
In a bowl mix:
1/2 cup salt
1/2 cup baking soda
1 full cup white distilled vinegar

Mix this well, it will fizz and bubble, so you know that has to be doing something!

Pour this mix down each drain.

Let this sit overnight.

The next morning pour hot water down the drain, which should clear out all of the drain fly eggs.

That's it!

Hope this helps!

Put the baking soda and salt down the drain first. Then pour in the vinegar. Quickly cover the drain and let set for at least 2 hours but overnight is best. Flush with boiling water. It could possibly take more than one treatment. Also, red wine mixed with a few drops of dish liquid makes a better trap. I had a terrible time with drain flies and these tips really work.

I live in an RV. I had these gnats flying around my home for weeks. I would find them dead and alive in my bathtub . I didn't know where they were coming from until I watched this video. The gnats we're aggravated when I ran my AC. I actually thought they were coming through the AC somehow. I followed the instructions on the video. I took out my AC filters and scrubbed them. After I poured the solution down the bathtub drain and toilet black tank. I let it sit over night. I poured the boiling water in and let it sit for 2 hours. Then dumped both the grey and black water tanks. I have been running the AC and so far no more gnats. Thank you for the video.

Thanks for showing this step by step. Doing the science experiment now. I thought the flies were fruit flies til I found out drain flies were a thing.

Boiling water down the drain 3 days in a row did it for me

[TupacAShakurAfeni]

Thank you!! I did this process for 1 week and they were gone. They came back, I treated again and they are fine! YOU ROCKSTAR!

[jamiemillians]

I'm back again!! One of these salutations worked last year for me. I had drain flies in my master bathroom from the toilet. I was amazed that this worked. Thank you!!!

I have used the salt, soda, vinegar solution for slow moving drains. No soap. I leave the solution in the drain for at least 20 minutes while I boil a gallon of water. Sometimes it takes 2 pots of boiling water. Clears the drain without hurting the pipes, I hope. Thank you for the video. Can't imagine your pain with 10 stitches! Hope it has healed quickly for you.

I use apple cider vinegar by itself with the mother in it. Pour into glass and fill to one inch. Get clear plastic wrap and cover the top of the glass with it and use a rubber band to keep it tight. Then poke one hole in the top and set around kitchen. They are drawn to it big time. I usually set about six of them around my home.
But I am going to try this gentleman's recipe now.

Thanks guy, had some work done on our bathroom pipes, started seeing those almost immediately. Now, I know what to do. TY

[rodzillarox]

Thanks brother . I have hundred of these things and i got a ton with a vaccum hose. Now making the mixture u suggested

[HopeBromleyFitGrasshopper]

Thank you 🙏! I have a small condiment bowl with a hole in the top with Apple cider vinegar and 1 drop dish soap and it is catching them but I keep seeing more every day lol. So I have assumed they are coming from the drains in my apt. I will have to do this for my bathroom and kitchen sinks. I appreciate the how to video! 🎊

Hey bud, Nice tips for pest control in general. But the only way to eliminate sewer flies for good, is to repair the breach that is in contact with the soil. I am a sewer inspector for over 30 years and this is the only way to eliminate the source of the problem. Most topical agents like the ones you shared will never reach the middle and upper sections of main drain or sewer line, Although they will likely kill any actual flies in or near the secondary traps. For the main drain or sewer lines, a topical agent would need to be delivered with some type of foaming product that would cover the entire surface of the inside of the pipe. The guy in the HOA needs to contract a Sewer inspector with a camera to identify the source of the break. Once repaired, flies are gone. Cheers

[cynthiariversmartinez]

TY! I am doing this but I noticed that they are breeding and some are in washcloths and towels. How do I get them out??

[-southcarolina]

Going to give this a try I live in an RV I hope it works thanks

If you have a garbage disposal, I believe it's better to mix the baking soda and vinegar in the drain. Pouring it down the drain after much of the chemical reaction has occurred in the bowl seems to prevent one from being able to effectively coat the outer edges of the disposal.

Just a suggestion, but I believe the foaming reaction is what allows you to coat the entire surface area

My family and I just moved into a house and I opened the toilet and there were drain fly larve in the toilet, what can I do? I flushed them down and haven’t seen any since. Should I be worried?

For my camper, I put about two inches of apple cider vinegar in a big clean whipped topping bowel and sat it in bathtub and closed the door and caught about a hundred drain flies in it. I did an experiment and I killed more using just apple cider vinegar.
Also put it under a light in kitchen sink and they are attracted to light and white bowels I found out.
How I got the drain flies was I paid my neighbor $20 to weed eat around my hook up since I was away from my camper most of the summer. He cut my sewage hose and it was leaking black tank when I pulled the tank for a week before I could order and replace it. I left my gray tank open and they came up in it that way. So if that happens to you don’t leave any tanks open until you can fix the problem. And treat the grown with a water and soapy bleach solution where sewage was outside. I cover my kitchen sink drains so I realized where they were coming from. My stupid neighbor could have told me he cut the sewage line but he is acting like he did nothing. Werid.
But the smell was terrible, so I used a couple mason jars and put scran wrap over the top and lid around edges and pokes holes in it and caught about 50-100 and didn’t have to smell the apple cider vinegar.

I agree I put the Baking soda and salt first kinda shake it down the drain a little and the add the vinegar it really works great plus it cleans your drain and drain pipes. But also check and make sure you don'y have a broken pipe in your plumbing. You will never get rid of the drain flies until it's fixed they can lay 30 to 200 eggs per day they live for only 2 weeks and the will make nest in your furinture your bedding and window tracts. the are drawn to light. don't use boiling water just really hot water boiling water may cause damage to you PVC pipes as they are plastic...

[jenniferw]

Apple cider vinegar and soap works really well.
